Remember back in college at the end of the semester, when it became time to get pennies on the dollar back for those expensive books at the start of the semester? Well, what Textbook Buy Back Comparison is trying to do is to help college freshmen suckered into actually buying the books for their classes users of all kinds get a few more pennies back â€“ if not more â€“ for their books. Users scan the book’s barcode or ISBN into the app, and then the app looks up websites that buy back books, showing who will buy it for the most money. This is a great opportunity for college students to use some of that education they got to get more of their parents’ money back for buying more beer books for next semester. The best part is that Textbook Buy Back Comparison is free, because those looking to maximize value on the books they’re selling back have no money to spend on apps! I think. In order to sell back books, one has to actually buy the books. That usually helps.
